This is solely a revenue gain -- even if it legal to make a right turn on red, you must have a stopwatch on your person?
The crooked county officials could easily just put up a "no right turn on red" sign, alleviating the aggravation of a motorist counting too fast. But no, gotta get those bucks.
I used to follow this stuff really closely. There was one camera in the Chicago area that had the proud distinction of every single ticket it wrote was for failure to come to a full and complete stop before making a right hand turn. And this was a road where there was very little cross traffic and vision was clear for a very long way. i.e. it should have been a “right turn yield” sign anyway.
There is one on the route to return rental cars to O’hare that is brutal. People are in a hurry. There’s obviously no traffic, and they nail you. It almost nailed me once and I knew it was there!
